Michigan summers push your engine’s cooling system hard. When it starts to fail, you might notice a slow coolant leak, a thermostat that sticks, or a radiator that can’t keep up. When this happens, temperatures climb fast and engine damage follows quickly. At Luai’s Automotive in Commerce Township, MI, our ASE-certified technicians diagnose and repair cooling systems on all makes and models, catching problems before they become costly repairs.
We always offer free inspections, and written estimates are included on all cooling system repairs.
Cooling System Repair Services in Commerce Township, MI
Your vehicle’s cooling system circulates coolant through the engine block and out to the radiator, where heat is released. Every component in that loop matters. When one fails, the entire system is compromised. Luai’s Automotive provides a full range of cooling services at our Commerce Township location, including:
- Radiator repair and replacement — a cracked, corroded, or clogged radiator can’t dissipate heat efficiently, leading to overheating
- Coolant flush and refill — old coolant becomes acidic and corrodes cooling system components from the inside out
- Thermostat replacement — a stuck thermostat prevents proper temperature regulation and affects both engine performance and cabin heat
- Water pump repair and replacement — the water pump keeps coolant circulating; when it fails, coolant stops moving through the system
- Coolant hose replacement — cracked or soft hoses can collapse and cut off coolant flow entirely
- Refrigerant leak detection and repair — we locate and repair coolant and AC refrigerant leaks before recharging or refilling
- Heater core repair — a leaking heater core causes poor cabin heat, a sweet smell inside the vehicle, and unexplained coolant loss
- Radiator cap replacement — a failing pressure cap allows coolant to escape and can cause overheating at lower temperatures
- AC system service — refrigerant recharge, compressor inspection, and cooling performance restoration
Warning Signs Your Cooling System Needs Repair
Cooling system problems rarely fix themselves. Catching the warning signs early is the difference between a straightforward repair and a blown head gasket. Bring your vehicle to Luai’s Automotive in Commerce Township if you notice:
- The temperature gauge reading higher than normal
- Steam or smoke coming from under the hood
- Coolant puddles under your parked vehicle
- A sweet or syrupy smell inside or outside the car
- The low coolant warning light on your dashboard
- Unusual noises from the engine bay, such as gurgling or knocking sounds can indicate coolant flow problems
- Milky or discolored oil, this is a sign of coolant mixing with engine oil, often from a head gasket failure
- Poor cabin heat during Michigan winters
Air Conditioning and Cooling System Service
Your vehicle’s AC system and engine cooling system are separate but closely related. Both manage heat, and problems in one can affect the other. At Luai’s Automotive, we handle both the heating and air conditioner systems. If your AC is blowing warm air, your refrigerant is low, or your compressor isn’t engaging, our technicians diagnose and repair the full AC system alongside any engine cooling work. Handling both in one visit saves time and keeps your vehicle comfortable and reliable through Michigan’s summer heat.

Frequently Asked Questions
How often should I have my coolant flushed?
Most manufacturers recommend a coolant flush every 30,000 to 50,000 miles, though some vehicles with extended-life coolant can go longer. Check your owner’s manual or ask our technicians. If you’re not sure when yours was last done, we can inspect the coolant condition and let you know where things stand.
Can I drive to the shop if my engine is overheating?
No. Driving an overheating engine, even for a short distance, can cause permanent damage; warped cylinder heads and seized engines are possible consequences. If your temperature gauge spikes or you see steam, pull over safely and turn the engine off. Call Luai’s Automotive at (248) 896-2243 and we can help you arrange a tow to our Commerce Township shop.
What causes a radiator to fail?
The most common causes are corrosion from old or contaminated coolant, physical damage from road debris, and clogging from scale buildup over time. Michigan road conditions can also cause cracks in the radiator from debris impact. Regular coolant flushes and inspections are the best way to extend radiator life and catch early signs of damage.
What’s the difference between a coolant leak and an AC refrigerant leak?
Coolant leaks come from the engine cooling system, including hoses, the radiator, the water pump, or the heater core. Refrigerant leaks come from the AC system. Both can cause performance issues and both need to be located and repaired before the system is refilled. Our technicians test for both and address each separately.
Do you work on all makes and models?
Yes. Luai’s Automotive services all makes and models at our Commerce Township location. Call us at (248) 896-2243 if you have questions about your specific vehicle.
